| Abstract: | Image encryption is enjoying more and more attention in information security filed.This paper researches on digital image combining encryption method based on optical transformation and classical scrambling transformation.The double random phase encryption method based on optical transformation is firstly introduced,then geometrical transformation methods such as the Arnold transformation and chaotic encryption are described.Last,this paper realizes image combining encryption by means of three kinds of encryption method.Experimental results show that this combining encryption method is more secure. |
